MACHINE FOR INSERTIN'G LACINGFHOOKS.

Application filed May 7, 1921. Serial No. 4616421..

To aZZ whom it may concern:

Be it known that I, VVERNER 0011s, a citizen of the German Republic, residing at Bad Liebenstein, Germany, have invented certain new and useful Improvements in orRelating to Machines for Inserting LacingHooks, of which the following is a specification.

The type of manually operated lacing hook setting machines which are now in general use and particularly those which are hand operated usually comprise extensive lever transmissions and other complicated mechanisms for producing the force necessary in fianging the hooks.

It is therefore the object of this invention to provide a lacing hook-setting machine of comparatively simple construction so that the hooks may still be efficiently flanged without requiring the complicated mechanism in general use. i 1

In order that the invention may be clearly understood, a machine in accordance therewith is described with reference to the accompanying drawings, wherein Fig. 1 i s-an elevation of the machine, the.

cover be1ng removed and the several parts being shown in their initial positions.

Fig. 2 is a section on line A-B of Fig. 1.

Figs. 3 to 6 are similar views as Fig. 1 showing the mechanism in four different working positions.

Fig. 7 is a section on line C-D of Fig. 1'.

Figs. 8 and 9 show a certain mechanism in two different positions.

F lg. 10 is a detail view of another part of the machine, drawn on a smaller, scale.

Referring to Fig. 1 1 is a casing, 2 a cover therefor and 3 a shaft mounted in said casing and adapted to be revolved by means of a lever ll .Upon said shaft 3 and insidethe case 1 a'lever which is provided with arms 6 and 7 is mounted and said lever is held in normal position by a spring 5. The arm 7 of the lever is connected with a set lever 10 by means of two links 9-9 adapted to pivot around the pin 8. The horizontal" lever 10 has a pivot pin 11 for the links 9-9, said lever 10 being pivotally mounted upon a bolt 13'fixed in the eye 14 of a slide 15. An abutment 12 serves for limiting the oscillatory movement of the lever 10. The slide 15 is movably mounted upon a guide piece 16 fixed in the case 1 said slide presenting at the upper end a small catch 17 with which correspondsanotch 18 (see Fig. 5) at the outer edge of a set 20 which is. removably an open slot- 19 (see Fig. 1). The dimensions of the slot 19 depend'on the size of the lacing hooks, the depth ofsaid slot corresponding to the width ofthe head of the lacing hooks, so that only one lacing hook at a'time can be lodged 'in'the set '20.

A ridge 21 is formed'upon the set 20 and extendsup into the slot 19, said ridge formmg, in the position of the different parts which isshown in Fig. '1, viz," the normal position of rest,-an'- extension of a rail 22 which extends through the opening 23 of the case 1 to the surface 24; of said case, and is connected with the reservoir for the lacing hooks; The lacing hooks 25 are automatically takenfrom a reservoir which can be of any convenient shape and construction and are fed to the opening 23 by means of the rail 22 whichis inclined.

The lateral surfaces of the removable set 20 slide along the surfaces 242 and 26 of the case which form the walls of a slot 27 arranged in the case 1. In order to'cover'the opening 23 during the movements of the horizontal lever 10 a curved slide 30 of L- shaped. cross section is mounted upon a cr-a nked arm 29 adapted to rotate in a central boring of the case 1, said slide 30 being continuously pulled against the set 20 by means of a spring attached on the one hand to the shoulder 31 of the slide and on the other hand to a hook 32 of the horizontal lever 10 so that said slide movedtogether with the said horizontal lever 10. I A pawl '36 pivota-lly mounted-upon the pin 35 of the guide rail 16 has a curved eXtension 37 which is continuouslypressed to theleft by means of a blade spring 39' fixed at 38 to the case 1. The pawl 36 has a notch 40 at its straight end (left hand end injFig. 1) designed to engageunder s in 11 of the slide 15 (see Fig. 4:), when said slide is in its highest position so that said pawl locksthe slide in this position. i

In a ridge 42' of the cover 2 of the case a pin-45 influenced by a spring 44 is movably can be accurately adjusted in vertical direction by means of a regulating screw 52. As the shaft of the riveting punch 51 is eccentrio and as the arm 49 can oscillate around the stud 4L7 the position of the riveting'set' can be regulated so that it stands always exactly over the centre of the shaft of the lacing hook. p v

The machine works in the following manner:-

In the normal position or position of rest (Fig. 1) the first of the lacing hooks riding upon the inclined rail 22 has reached the ridge 21 of the set 20. If now the hand lever 4: is moved in the direction of the arrow (Fig. 1) the shaft 3 carrying the arms is turned so that the horizontal lever 10 with the set 20 and with the lacing hook 25 riding upon said set are brought into the position shown in Fig. 3, the set 20 bearing against the slide piece 15 andthe notch 18 of the set 20 engaging with notch 17 of said slide piece so that the lacing hook 25 is securely held in the pincers thus formed. The curved slide 30 is drawn along by the lever 10 so that the arm of said curved slide which is directed towards the centre of the case closes the opening 23 of the case against the lacing hooks upon the rail 22 (Fig. 9).

By further moving the lever 4: in the direction of the arrow (Fig. 3) the toggle consisting of the arm 7 andof the links 99 is gradually stretched whereby the lever 10 with the set 20 is advanced so that the shaft of the lacing hook 25 riding upon the set 20 is pressed against the riveting set 51. The slide piece 15 is also advanced owing to the lever 10 being pivotally connected with the eye 14 of said slide piece sothat these parts adopt the position shown in Fig. 4 in which the toggle 79 exerts its maximum pressing effort. The shaft of the lacing hook has been inserted, shortly before the position shown in Fig. 4 has been reached, into the hole of the upper 53 placed upon the riveting set 51, whereupon said shaft is flanged under high pressure. The slide 30 remains in the position Fig. 3 whilst the other parts are in the position Fig. 41-, that is to say when the toggle 79 is completely stretched.

The notch 40 of the pawl 36 engages under the pin 41 of the slide piece 15 when the different parts are in the position shown in Fig. 1 so that the slide piece and conse quently also the lever 10 and the set :20 are locked in their highest position. When the hand lever 4 is released, the spring 5 causes the shaft 3 to turn in the opposite direction, whereby the toggle 7-9 is bent. As the slide piece 15 is however locked. the bending of the toggle 7-9 provokes merely an oscillation of the lever 10 around the pivot bolt 13 in the manner shown in Fig. 5 so that the lacing hook which has just been fixed in the upper is released by the set 20. lVhen the toggle has assumed the position shown in Fig. 5, the arm 6 begins to act upon the curved rear arm 37 of the pawl so that this pawl is pivoted against the action of the spring 39 and releases the pin 41 so that the slide piece 15 is liberated.

From the preceding description it is clear that the slide piece 15 was prevented from being influenced by the movement of the lever 10 before the different parts have adopted the positions shown in Fig. 5.

WVhen the shaft 3 continues to turn in the direction of the arrow (Fig. 5), the slide 80 piece 15 is first pulled back (Fig. 6) so that the upper 53 becomes free and can be removed from the riveting set 51. r

The return of the shaft 3 to its normal position shown in Fig. 1 causes the return of all the parts to the normal positions so that the opening of the case which had been closed by the slide 30 becomes free, the ridge 21 of the set 20 again comes into alignment with the inclined rail 22 (Fig. 8) and the first of the lacing hooks upon said rail 22 can slide upon the ridge 21 so that the work can again he proceeded with. The feeding device for the lacing hooks can be of any convenient construction and the machine can also be worked by mechanical power.
